Unique Entity Identifier Replaces DUNS Numbers
Any company planning to work with the federal government should have a Unique Entity ID.
UEIs Replace DUNS Numbers
As of April 4, 2022 the federal government eliminated the use of the DUNS Number and is now utilizing the Unique Entity Identifier (UEI) to serve as its replacement. By rolling out the UEI, the government can streamline the business identification process without relying on a third party.
What is a Unique Entity Identifier (UEI)?
The UEI is a 12-character alphanumeric ID that will be assigned to public/private companies, individuals, non-profit entities, governments and other organizations planning to apply for government contracts and grants. The UEI has completely replaced the previously used DUNS number as the primary entity identifier for federal awards and contracts.
How to obtain a Unique Entity Identifier (UEI)?
To register your business and to obtain a UEI, see www.SAM.gov (System for Award Management).
For more information about obtaining a UEI, you can read our blog Doing Business with the Government and UEIs.
How much does it cost to get a Unique Entity Identifier?
The Unique Entity Identifier (UEI) is free when registering online at www.SAM.gov.
How long does it take to get a UEI number?
After registering for your UEI number on www.SAM.gov, it may take anywhere from 10 to 12 days before becoming available to the business owner. Your assigned UEI will be visible on www.SAM.gov once complete.
How do I look up my UEI number?
If your entity is already registered with the federal government, you can look up your UEI by logging into your www.SAM.gov account. Once logged in, go to the "Entity Registration" section of your account and your UEI will be listed under your entity information, alongside other entity details such as name, address, and registration status.
Do I need to renew my UEI?
The UEI itself does not expire, but your www.SAM.gov registration must be renewed annually to remain active. If your registration lapses, your entity will be marked as inactive, and you will not be eligible for new federal contracts, grants, or financial assistance.

Frequently Asked Questions
A DUNS number (Data Universal Numbering System) was a unique nine-digit identification number that verified the existence of a business, globally. It was assigned by Dun & Bradstreet (D&B) for each physical location of a business and was used by industries and organizations around the world as a global standard for business identification and tracking.
Your DUNS number was associated with a "Paydex" score, from 0 to 100. 75 and above is considered an excellent score. This score was compared to a business credit score in that it is a predictor of prompt bill payment.
Once you have an account, you can check your score online.
You needed a DUNS number for your business if you planned to:
- Provide contract work for any government organizations
- Get approved for a business line of credit
- Work with specific industry and trade associations
- Separate your personal assets from your business
Oftentimes if you marketed that you are listed with D&B and had a great score, it could be the determining factor on whether or not you attracted a client's business.
Typically, business owners register for a number with Dun & Bradstreet following the legal formation of their company. This is done so the number would be connected to their company directly and not to their personal credit. Attaching it to your personal credit could possibly lower your score.
D&B required the following information about your company:
- Business name
- Physical mailing address
- Company formation date
- Nature of the business
- Name(s) of principal(s)
- Industry classifications (i.e., SIC, NAICS)
- Payment and financial experiences
Typically, your DUNS number arrived via mail 45 days after you registered. However, you also could have purchased an expedited process and your number would have arrived within five business days.
The DUNS number was free. However, if you wished to receive your number faster than the standard 45 days, you could have purchased an expedited process from D&B for $229.
There were a few different ways to get a DUNS number. You could have visited D&B's DUNSFile page or called 1-866-374-0441.
